Hey all, so I've got a bit of a dilemma. I have a 1995 Mercury Cougar that just refuses to shift. First off, it's automatic, just to be sure we're all on the same page. When I put it any gear, it's almost as though it's in neutral until I put my foot in it and get it up to about 3000 to 3500 rpm. And even then, it stays in first gear. Additionally, it usually has fairly high rpms and kicks when shifting from second to third sometimes. No other problems that I can tell. Plenty of fluid, doesn't smell burnt. I was thinking it might be the ECU, but that doesn't seem likely since the shifting problems are the only issue present. Oh, unsure if this is related, but when I start it up at the beginning of the day, the low coolant light comes on. I have plenty of coolant in there, and after it runs for a bit, the light shuts off on it's own.
